Cross-linked Poly(arylene ether ketone) containing highly sulfonated pendant groups for proton exchange membrane |
| 초록 |
Poly(arylene ether ketone) was synthesized containing pendant carboxylic groups which could produce a series of cross-linked sulfonated poly(arylene ether ketone). In order to limit the harmful degradation of sulfonated groups on the main chain and to make it more stable in working condition, sulfonated groups were attached on the diamino cross-linker and pendant amino naphthalene. In addition, sulfonated cross-linker was utilized to enhance proton conductivity and mechanical properties but lower the water uptake. Grafting of sulfonated groups onto the PAEK main chain could control the ion exchange capacity and thus could tune the properties of the polymer by controlling the degree of substitution. Proton conductivity, water uptake, thermal stability, mechanical properties of the cSPAEK membranes were investigated to evaluate their possible application for fuel cell. |
